The document is a technical datasheet for the National Semiconductor F100170 Universal Demultiplexer/Decoder. It describes how the device functions as either a dual 1-of-4 decoder or a single 1-of-8 decoder based on the Mode Control (M) input signal.
The datasheet provides comprehensive electrical specifications, including absolute maximum ratings and DC characteristics for operating voltages ranging from -4.2V to -5.7V. It also includes AC electrical characteristics such as propagation delay times for various inputs at different temperatures.
| Operating Voltage Range | -4.2V to -5.7V |
|---|---|
| Case Temperature under Bias | -65°C to +85°C |
| Storage Temperature Range | -65°C to +150°C |
| Maximum Junction Temperature | +150°C |
| Output HIGH Voltage (Typical) | -955 mV |
In the dual mode, each half has a pair of active-LOW Enable (E) inputs.
Signals applied to auxiliary inputs Ha, Hy and He determine whether the outputs are active HIGH or active LOW.
